Once again, jet motors will not work in this river. There is a LOT of fine suspended silts and sugar sands that will eat up a jet impeller rather...
I've seen those National Guard Bridging Unit jet boats in action. A little too big and heavy for what I need, plus it takes an experienced crew...
Yep, that boat is almost perfect! That's what I'm looking for. I'd maybe make the tunnel a little narrower - I think 14 inches would probably...
Yes, I realize the buoyancy would be less with the tunnel, but the tunnel will still allow shallower running. Every inch makes a huge difference...
Yep, that's almost exactly what I'm talking about! :)
I'm still not sure what advantage your system has, Tom. I can see where it might protect the motor (and transom to a degree) if one should hit an...
Poor capacity/power ratio, high maintenance. They are considered airboats and thus are not legal to run on this stretch of the river (considered...
Thank you all for the responses. As I've said, we have a 19-foot jon with a 54-inch bottom width (around 60-inch top width), and it seems to be...
I chose five feet width as a compromise. Narrower could lead to stability problems and wider may unnecessarily increase weight. We currently...
I need a boat for working on sandbars in the river. The boat needs to be lightweight (so we can push it off of submerged sandbars), able to run...
I think the idea is valid. I don't think we currently have the technology to implement it in a satisfactory fashion. Perhaps the final propulsor...
It is perfectly valid to argue that cetaceans developed horizontal tails due to evolving from (possibly) terrestrial mammals, as much as they have...
As a fisheries biologist, I'll just add a few thoughts here... Most fish do use their entire bodies for forward locomotion, although it is to...
Methinks one could devise a simple propulsive fin for something like a canoe (I select this because of it's long, narrow efficient design, and...
